A domestic dispute between two brothers-in-law escalated into a physical fight late Friday night — leaving one man with stab wounds and another man with a portion of his ear bitten off.

Rochester police said Delmar Grice, 36, of Rochester, and Charles Switzer, 38, of Irondequoit, were both arrested and will be facing assault charges after the altercation, which took place about 11:50 p.m. on Sayne Street in Rochester.

Grice appeared to have a portion of his ear bitten off during the fight, police said. He was taken to Rochester General Hospital for his injuries.

Switzer had stab wounds to his face and torso, police said. He was taken to Strong Memorial Hospital to be treated.
